How Can I Parameterize Page Elements for a Test?

Question

I am looking to parameterize some tests and the only thing that changes in the tests are slider elements on the page. Here is what I was thinking of doing, just not sure how to get it over the line and working. I have tried looking at different examples but they only show how to do it if you are looking for a different string in the element. Below is my example:

    [TestCase(amountTab.GreaterEqual3DSSliderValue.Text, amountTab.GreaterEqual3SDSlider)]
    public void ParameterizeMoveAmountSliders(IWebElement sliderValue, IWebElement slider)
    {
        var statsPage = new AdminStatisticsPage(LufasWebManager.Driver);
        statsPage.IsAt();
        var statsDashboard = new AdminStatisticsDashboardSubpage(LufasWebManager.Driver);
        statsDashboard.IsAt();
        statsDashboard.ClickUniversalSettingsCard();
        var configurationTab = new AdminStatsConfigurationSubPage(LufasWebManager.Driver);
        configurationTab.ClickAmountTab();
        var amountTab = new AdminStatsAmountSubPage(LufasWebManager.Driver);
        LufasWebManager.WaitUntilElementExists(5000, amountTab.GreaterEqualNeg1SDSlider);
        var currentSliderValue = sliderValue;
        configurationTab.MoveSliderLeft(slider, 3);
        var updatedSliderValue = sliderValue;
        Assert.AreNotEqual(currentSliderValue, updatedSliderValue);
    }

You can try using TestCaseSource attribute (or similar approach with TestCaseData one). Something along the lines:

[TestCaseSource(nameof(ParameterizeMoveAmountSlidersCases))]
public void ParameterizeMoveAmountSliders(Func<AdminStatsAmountSubPage, IWebElement> sliderValue,
    Func<AdminStatsAmountSubPage, IWebElement> slider)
{
    var statsPage = new AdminStatisticsPage(LufasWebManager.Driver);
    statsPage.IsAt();
    var statsDashboard = new AdminStatisticsDashboardSubpage(LufasWebManager.Driver);
    statsDashboard.IsAt();
    statsDashboard.ClickUniversalSettingsCard();
    var configurationTab = new AdminStatsConfigurationSubPage(LufasWebManager.Driver);
    configurationTab.ClickAmountTab();
    var amountTab = new AdminStatsAmountSubPage(LufasWebManager.Driver);
    LufasWebManager.WaitUntilElementExists(5000, amountTab.GreaterEqualNeg1SDSlider);
    var currentSliderValue = sliderValue(amountTab);
    configurationTab.MoveSliderLeft(slider(amountTab), 3);
    var updatedSliderValue = sliderValue(amountTab);
    Assert.AreNotEqual(currentSliderValue, updatedSliderValue);
}

public static IEnumerable<object> ParameterizeMoveAmountSlidersCases =  new object[]
{
    new Func<AdminStatsAmountSubPage, IWebElement>[] { amountTab => amountTab.GreaterEqual3DSSliderValue.Text, amountTab => amountTab.GreaterEqual3SDSlider },
};
